Well, my tired eyes must need some sleep, because I seem to have glazed right over that when reading that. I was getting bothered at the fact that at one point it says, " It returns a reference to an array containing a reference to an array (or hash, see below)" and was thinking, "See below where?!" Turns out I either need glasses or some sleep. Thanks for clearing that up for me.

I did do a print Dumper on it, and what I was seeing was a hash, but somewhere I read in the documentation (trying to find it now) that it returns "a reference to an array of array refs," and my brain was thinking, "Wow, so somehow a reference to an array of array refs becomes a hash?" Silly brain.
